Mumble now officially supports Windows, Linux and Macs (OSX i386 & PPC)

Mumble is similar to gaimg VoIP systems such as Teamspeak, Roger-Wilco and Ventrillo but incorporates the lastest high-quality Speex codec which allows for crystal-clear sound and automatic gain control.

In software terms, Mumble is the client component and Murmur is the server. Mumble allows for a graphics overlay when full-screen gaming to show who is talking. There is also provision for communication between Mumble and game engines to allow automatic changing of teams and in-game ‘spatial’ voice.
